FRANK HOLUB AND CHARLES S. LOOKE, OF CHICAGO, ILLINOIS.

MACHINE FOR CREASING, PUNCHING, AND SWAGING HORSESHOE-BLANKS.

SPECIFICATION forming part of Letters Patent No. 227,009, dated April 2'7, 1880.

Application filed December 8, 1879. I

To all whom it may concern:

Be it known that we, FRANK HOLUB and GHARLEs S. LOCKE, both of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Oreasing, Punching, and Swaging Horses hoeBlanks, of which the following is a specification.

The object of our invention is to prepare a horseshoe-blank as it comes from the rollingmill for the final operation of bending, shaping, and completing the shoe.

In another patent of even date herewith we have shown a machine for finishing the shoes after the blanks have been treated by the mechanism herein shown, and in both patents the construction of the main frame-work and driving-gearing is the same.

- In the accompanying drawings, which illustrate our invention in the form now best known to us, Figure 1 is a plan view. Fig.2 is a section on the line 2 2 of Fig. 1. Figs. 3 and 4 are views of the blanks at different stages of the operation.

The operation of the gearing will be well understood by an inspection of the drawings, and need not therefore be described.

Upon the main frame A a supplementary frame, B, is mounted. A reciprocating bedplate, 0, which receives its motion through a pitman, D, pivoted to a slotted crank-arm, E, that is worked by a wrist-pin, 6, upon one of the gear-wheels, slides upon ways I) in the frame B. This frame is provided with vertical friction-rollers b and strong horizontal supporting friction-rollers b Thus far the construction of the machine is in all respects identical with that shown in our patent hereinbefore referred to.

The bed-plate has upon its upper surface suitable guide-blocks c and a guide-bar, 0, between which the blanks are to be fed to the machine. The inner edges of these blocks are beveled, as at 0 for the reception of correspondingly-shaped sliding forging or swaging hammers F. Upon these hammers, near the frame B, suitable rollers, f, are mounted, which, as the bed-plate advances, come in contact with the rollers G G G mounted in the supplementary frame and projecting into their path. The first of these rollers, Gr, projects but slightly, the second, G, a little farther, and the third, G still farther. Thus three successive blows are given to each hammer as the bed-plate advances.

the shoeblank rests while being swaged.

A laterally-sliding notched plate, II, works in a notch, h, in the bar 0, its movements being regulated by a pin, h, working in a guideway, I, mounted upon the frame B. The sliding swaging hammers are controlled by a switch, K, mounted upon the frame.

The dies for creasing and punching the blanks are formed upon an annular collar, L, two sets of dies, Z I, being shown. It is obvious, however, that as many as four or more might be formed upon the collar in a full-sized machine. This collaris mounted upon the top shaft, M, revolving above the bed-plate, and is adjustably secured thereon by means of a nut, N, which clamps it against a rigid collar, m, on the shaft.

By thus adjustably securing the collar upon its shaft we are enabled not only to adjust the dies relatively to the blanks to be fed to the machine, but also, should one set of dies become worn or broken, to bring another set into position without delaying the working of the machine.

The operation of the machine thus far described is as follows: Supposing the bed-plate to be in position at the feeding end X of the machine, the hammers will be drawn back by their switch, and the notched plate will project from the guide-bar a. A blank should now be slid onto the bed-plate until the toecalk thereon enters the notch in the plate H. As the bed-plate advances the hammer farthest from the feeding endof the machine will swage one end of the blank, as described, and as the blank passes under the creasing and punching dies the plate H will be withdrawn from over it and the toe-calk will enter the notch Z in the collar L, the remaining end of the blank being swaged by the second hammer just before it leaves the dies.

The blanks are delivered from the machine by the same mechanism as the finished shoe is in our patent hereinbefore referred to, which mechanism consists of a rotary cam, 0, upon the end of the shaft M, which operates a weighted lever, P, connected to another lever, Q, which Works a hook, R,'pivoted upon an arm extending from the frame B. The motion of this hook is so timed that as the bed-plate reaches the end of its forward movement it drops over the toe-call; on the blank and holds it until the bed-plate, upon its return movement, passes from under it, when the blank drops into a suitable receptacle.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbefore set forth, of the reciprocating bedplate, the guides c 0 upon the bed-plate, the notched plate H, its guideway, and the creasing and punching dies.

2. The combination, substantially as hereinbet'ore set forth, of the bed-plate, the guides c 0 upon the bed-plate, the sliding hammers, and the rollers projecting into the path of the hammers.

3. The combination, substantially as hereinbefore set forth, of the bed-plate, the guides 0 0 upon the bed-plate, the sliding hammers, the rollers projecting into the path of the hammers, and the creasing and punching dies.

4. The combination, substantially as hereinbefore set forth, of the bed-plate, the guides 0 0 upon the bed-plate, the notched plate H, its guideway, the hammers, and the rollers projecting into the path of the hammers.

5. The combination, substantially as hereinbefore set forth, of the bed-plate, the guides c 0 upon the bed-plate, the notched plate H, its guide-slot, the hammers, the rollers projecting into the path of the hammers, and the creasing and punching dies.

In testimony whereof we have hereunto subscribed our names.
